I’ve been using a urethane clearcoat to seal the last coupla boards I’ve done. Same problem in varying degrees on every one. I have been having a problem with fisheye. I sand the hot coats to 400 wet with a drop of dish soap to get clean. I clean with acryliclean and wipe down before I spray. I use an oiless compressor with a filter at the gun. Thought it was contamination in my system but a recent repair I sprayed with clear Krylon had some fisheye also! Now I’m thinking it is wax from the SA that is causing this. Anyone have a good way to clean ALL the wax off and out of the pin holes before applying the spray? I used to do auto painting so the wetsand/soap/acryliclean has always worked well…not so on fiberglass!
